I-55 Design Build
Traversing the cities of Pevely, Herculaneum, Festus, and Crystal City, Missouri, this project addresses traffic and safety concerns along the I-55 corridor and helps leaders prepare for future development and growth patterns in the region. I-55 is one of the heaviest traveled interstates in Missouri, with over 70,000 daily motorists and nearly 11,000 heavy trucks.
